Harmonic Highlights

  • Employs the “backdoor dominant” resolution (F7 to C6), utilizing the bVII7 to I movement common in late swing-era harmony.
  • Frequent use of secondary dominants, specifically A7 (VI7), to facilitate strong functional resolutions back to the ii chord (Dm7).
  • Structure is built upon extended ii-V-I sequences in C major, maintaining a high harmonic rhythm of two chords per measure.
  • Derived from Ravel’s “Pavane pour une infante dĂ©funte,” the progression blends Impressionist root movements with traditional diatonic jazz cycling.

Improvisation Focus C Major Bebop Scale (integrating the chromatic passing tone between G and A to align chord tones on downbeats).

Difficulty Rating 2/5 — The predictable ii-V-I patterns and clear tonal center make it an ideal vehicle for intermediate players to practice functional voice leading.
